Why is my build plate z level getting messed up

Thank you for your response. I don't think it is the nozzle because it is a new printer. I wanted to ask you if you recommend any specific settings for support structures?

The nozzle can clog from a short time of running crappy filament, if your initial leveling was proper and the first couple layers were printed properly I would start with basic maintenance. My settings apply to S3D so I'm not sure if they would apply to Makerware.
